The latest document posted on Wikileaks, however, does not involve failed election running-mates, controversial right wing political parties, or controversial religious cults. Instead, Wikileaks itself has found itself exposed as guilty of an all-too-easy mistake when sending an email.

A careless blunder by an individual sending an email to potential donors to Wikileaks exposed 58 recipients email addresses by putting them in the CC: field rather than BCC:

True to its roots, Wikileaks has itself published the email containing all the addresses on its website after it was anonymously submitted – presumably to test the site’s declared aim of complete impartiality. I have blurred out the email addresses above, but Wikileaks has posted them in full.

Of course, Wikileaks is far from the first organisation to make this kind of screw-up, and we’ve discussed before how 70% of businesses are concerned about data leaking out via email. This is just one of the easiest ways in which data about your customers or partners can leak from your company, and potentially open them up to embarrassment or spam.

Ironically, the Wikileaks page making available the document also asks for donations for the Wikileaks project.
